Well I just looked and the OS is 1.8 oz lighter than the 82.

Plus the Saito 82 is just as light as a 46-50 twostroke
OS always claim the weight minus the muffler. They actually says the 91 fx weighs 550 grams, quite impressive huh? well mine on a digitale scale weighs exactly 770 grams, not quite so impressive anymore. I bet if you actually weigh the OS 50 all complete the difference will be minimal to the Saito 82. I 3-D my Harrier 46 and started out with the Magnum 52 XLS with the Tower muffler, then swiched to the MVVS 49 on the mini pipe and finally the Magnum 91 fourstroke, and although the 91 is heavier than the previous twostrokes it is MUCH better and improved my abilities with that plane alot. All engines had no problem pulling out of hover, but the fourstroke swinging a larger prop made just about every move easier
